摘要: A thin film transistor device reduced substantially—in resistance between the source and the drain by incorporating a silicide film, which is fabricated by a process comprising forming a gate insulator film and a gate contact on a silicon substrate, anodically oxidizing the gate contact, covering an exposed surface of the silicon semiconductor with a metal, and irradiating an intense light such as a laser beam to the metal film either from the upper side or from an insulator substrate side to allow the metal coating to react with silicon to obtain a silicide film.

摘要: A thin film transistor device incorporates a silicide film contacting the source and drain. The silicide layer substantially reduces parasitic resistance between the source and drain of the device, improving the performance of the TFT. The silicide layer may be formed by covering the silicon semiconductor with a metal and irradiating the metal with a laser to initiate a reaction with the adjacent silicon to produce a silicide film. The layer may also be formed by rigidly adhering a metal coating to the exposed source and drain regions using a triangular-shaped insulator, and allowing the metal to react with silicon.

摘要: Method of improving making contact with the source/drain regions of thin-film transistors. A substantially triangular insulator determines contacts with the source/drain regions by a self-aligning process. The width of this insulator can be determined without performing mask alignment. Furthermore, the width can be reduced. Therefore, the sheet resistance of the source/drain regions presents no serious problems.
